SPINNING-MACHINE.

Patented Nov. 3, 1908.

Application filed. May 16, 1906. Serial No. 317,227.

To all whom it may concern:

5; Be it known that I, JoHN JACKSON, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Spinning-Machines, of which the following is a specification.

This invention has reference to an improvement in spinning machines and more particularly to an improvement in mechanism for operating the separators of spinning machines.

The object of my invention is to improve the construction of mechanism by which the yarn separators of spinning machines are operated and controlled.

A further object of my invention is to simplify the construction of the mechanism for operating the se arators whereby the cost of manufacturing t e mechanism is reduced.

My invention consists in the peculiar and novel construction of mechanism adapted to operate and control the yarn separators of spinning machines, with details of constructlon, as will be more fully set forth hereinafter and claimed.

Figure 1 is a front view of portions of a spinning machine provided with my improved mechanism for operating the yarn separators and showing the ring rail in a central position and the separators in their 0 erative position. Fig. 2 is a vertical sectlonal view taken on line 2 2 of Fig. 1, showing the separators in their operative position in full lines, in the position for dofiin in broken lines, and the cam on the top rai for automatically throwing the separators into their operative positions. Fig. 3 is an enlarged transverse sectional view through the separator bar, looking at the bearing on the upper end of the actuating rod, showing the separator bar in an intermediate position and the greater part of the se I arator plate broken away and the stops for imiting the forward and backward movement of the separators. Fig. 4 is an enlarged vertical sectional View taken centrally through the separator bar and the bearing on the upper end of the actuating rod and showing the means for securing the separators to the bar and for rotatably supporting the bar in the bearing, and Fig. 5 is an enlarged detail view looking at the back and showing the means for operatively connecting the lower end of the actuating rod with t e lifter arm of the machine.

In the drawings, it indicates part of the end frame, 6 the bolster rail, 0 the ring rail, (1 the spindle, e the top rail, f the rock shaft, 9 the rock shaft bearing, h the lifter arm, 0. the lifter rod, is k the separator plates of a spinning machine and I my improved se arator operating mechanism comprising a racket bearing m, an aetuatin rod 07., a shoe 0 on the lower end of the re a roll p adjustably secured to the lifter arm'h, a'bearing s on the upper end of the actuating rod, a'separator bar t, and a cam plate '11 secured to the top rail e, as shown in Figs. 1 and 2.

The separator plates 7c k are each stamped from sheet metal in the usual form and shaped to have the ofi-set arm 6 with the flat L-shaped end 7 by which the separator late is rigidly secured to the separator bar t y a screw 8. A li 9 is formed on the forward edge of the en 7 which is adapted to engage with the front edge of the separator bar t and prevent the separator plates from turning on the bar.

The bearing bracket m has a forwardly-extending arm 10 on its lower end (strengthened by the web 1 1) by which'it is secured to the underside of the lower bolster rail by the bolt 12. The actuatin rod 12. is en ported in a vertical osition in t e bracket bearing an at the has of the bolster rail, as shown' in The shoe 0 has the flat bottom 13' stren thened by the rib 14 mergin "into the hu 15 which 1s adjustably secure to the lower end of the actuating rod 11. by a set bolt 16' in a position for the toe of the shoe to extend toward the rock shaft f, as shown in Fi 1.

The roll p is rotatably secured to a c amping arm 17 by a shouldered bolt 18. The clamping arm 17 is shaped to loosely fit the lifter arm 11. and is adjustably securedto the arm by a set bolt 19' in a. position for'the roll to engage with the flat bottom 13 of the shoe 0. as shown in Figs. 2 and 5.

The bearing 8 is cut away on one end to form the stop 20 and has the hub 21 adjustably secured to the upper end of the actuating rod n by a set bolt 22. Arotatable bushing 23 in the bearin is constructed to have the semi-circular co lar 24 at one end the ends of which form the stop shoulders 25 25 and a central longitudinal rectangular shaped hole 26 through which the separator bar 11 extends and in which it is secured by a set screw 27 in the collar 24, as shown in 4. A handle 28 may be secured to one end of the separator bar 15, as shown inFig. 1, for throwing the separator plates into the rearward position, as shown in broken lines in Fig. 2

or dofiing.

'The cam plate '0 is formed integral and has the downwardly-extending flat arm 29 which extends at a slight angle toward the center of the machine and merges into the upwardly and outwardly extending flat cam face 30 and the side arm 31 by which the cam plate is secured to the top rail 6 by a bolt 32 in a position for one of the separator plates is to engage With the cam plate, as shown in Figs. 1 and 2.

In the operation of my improved se arator actuating mechanism the separator ar t is en ported on two or more of the actuating re s n and their 0 erative parts. The separators are held in t eir operative positions by the forward sto shoulder 25 on the bushing 23 engaging witli the stop 20 on the bearin s, as shown in Fig. 2. The separator platesi It now have a vertical reciprocating motion corresponding to the motion of the ring rail 0 through the roll p, the shoe 0, the actuating rod n, the bushing 23 and the separator bar t. The separ'ator plates may be adjusted relative to the ring rail for different heights of bobbins by adjusting the shoe 0 on the lower end of the actuating rod n and adjusting the bearin s on the upper end of the actuating rod. lhe separator lates are thrown beyond the center into t eir backward or inoperative position for doffing, as shown in broken lines in Fig. 2 by a forward and upward movement of the handle 28 which partly rotates the se arator bar and bushings 1n the bearing 3. he separator plates are now held in their backward position supported by the rear sto shoulder 25 engaging with the sto 20. n the first upward movement of t e ring rail 0 and the separator plates 7c 7c the upper rounded end of one of the separator lates will engage first with the downwardl -extending arm 29 and then with the cam face 30 of the cam plate '0 which throws the separator plates beyond center toward the front, where they automatically assume their operative ositions between the bobbinsby gravity, or t e separators may be made to assume t eir operatlve positions by the downward movement of the handle 28.

B adjusting the roll p lengthwise on the li ter arm h a lesser or a greater vertical movement may be given to the separator plates.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
